Structures of Get3d reveal a distinct architecture associated with the emergence of photosynthesis.

Homologs of the protein Get3 have been identified in all domains yet remain to be fully characterized. In the eukaryotic cytoplasm, Get3 delivers tail-anchored (TA) integral membrane proteins, defined by a single transmembrane helix at their C terminus, to the endoplasmic reticulum. While most eukaryotes have a single Get3 gene, plants are notable for having multiple Get3 paralogs.

Measurement of kinetic isotope effects on peptide hydroxylation using MALDI-MS.

Primary kinetic isotope effects (KIEs) provide unique insight into enzymatic reactions, as they can reveal rate-limiting steps and detailed chemical mechanisms. HIF hydroxylases, part of a family of 2-oxoglutarate (2OG) oxygenases are central to the regulation of many crucial biological processes through O-sensing, but present a challenge to monitor due to the large size of the protein substrate and the similarity between native and hydroxylated substrate. MALDI-TOF MS is a convenient tool to measure peptide masses, which can also be used to measure the discontinuous kinetics of peptide hydroxylation for Factor Inhibiting HIF (FIH).

Quality Matters: Implementation Moderates Student Outcomes in the PATHS Curriculum.

Analyses of the relationship between levels of implementation and outcomes of school-based social and emotional learning (SEL) interventions are relatively infrequent and are typically narrowly focused. Thus, our objective was to assess the relationship between variability in a range of implementation dimensions and intervention outcomes in the Promoting Alternative Thinking Strategies (PATHS) curriculum. Implementation of PATHS was examined in 69 classrooms across 23 schools in the first year of a major randomized controlled trial.

A cluster randomized controlled trial of the Promoting Alternative Thinking Strategies (PATHS) curriculum.

This randomized controlled trial (RCT) evaluated the efficacy of the Promoting Alternative Thinking Strategies curriculum (PATHS; Kusche & Greenberg, 1994) as a means to improve children's social-emotional competence (assessed via the Social Skills Improvement System (SSIS); Gresham & Elliot, 2008) and mental health outcomes (assessed via the Strengths and Difficulties Questionnaire (SDQ); Goodman, 1997). Forty-five schools in Greater Manchester, England, were randomly assigned to treatment and control groups. Allocation was balanced by proportions of children eligible for free school meals and speaking English as an additional language via minimization.

Why Machiavellianism Matters in Childhood: The Relationship Between Children's Machiavellian Traits and Their Peer Interactions in a Natural Setting.

The current study investigated the association between Machiavellianism and children's peer interactions in the playground using observational methods. Primary school children (N = 34; 17 female), aged 9 to 11 years, completed the Kiddie Mach scale and were observed in natural play during 39 recesses (average observed time = 11.70 hours) over a full school year.

Evaluation of the implementation and impact of an integrated prevention model on the academic progress of students with disabilities.

In this paper we report on the implementation and impact of an integrated prevention model (Achievement for All - AfA) to improve the educational experiences and outcomes of students with disabilities. It comprises three inter-related strands: assessment, tracking and intervention; structured conversations with parents; and, developing provision for wider outcomes. Participants were 12,038 students with disabilities from 431 mainstream primary and secondary schools across 10 Local Authorities in England involved in the two-year AfA pilot.

Anatomical and physiological regulation of post-fire carbon and water exchange in canopies of two resprouting Eucalyptus species.

The great majority of Eucalyptus spp. are facultative resprouters, and they dominate the eucalypt forests of Australia. Despite this numeric and geographic dominance, there is a general lack of knowledge of their capacity for carbon capture and water loss during canopy reinstation.

Photosynthetic benefits of ultraviolet-A to Pimelea ligustrina, a woody shrub of sub-alpine Australia.

The definition of photosynthetically active radiation (Q) as the visible waveband (λ 400-700 nm) is a core assumption of much of modern plant biology and global models of carbon and water fluxes. On the other hand, much research has focused on potential mutation and damage to leaves caused by ultraviolet (UV) radiation (280-400 nm), and anatomical and physiological adaptations that help avoid such damage. Even so, plant responses to UV-A are poorly described and, until now, photosynthetic utilization of UV-A has not been elucidated under full light conditions in the field.

Achievement for All: improving psychosocial outcomes for students with special educational needs and disabilities.

Students with special educational needs and disabilities (SEND) are at a greatly increased risk of experiencing poor psychosocial outcomes. Developing effective interventions that address the cause of these outcomes has therefore become a major policy priority in recent years. We report on a national evaluation of the Achievement for All (AfA) programme that was designed to improve outcomes for students with SEND through: (1) academic assessment, tracking and intervention, (2) structured conversations with parents, and (3) developing provision to improve wider outcomes (e.

Investigating hypervigilance for social threat of lonely children.

The hypothesis that lonely children show hypervigilance for social threat was examined in a series of three studies that employed different methods including advanced eye-tracking technology. Hypervigilance for social threat was operationalized as hostility to ambiguously motivated social exclusion in a variation of the hostile attribution paradigm (Study 1), scores on the Children's Rejection-Sensitivity Questionnaire (Study 2), and visual attention to socially rejecting stimuli (Study 3). The participants were 185 children (11 years-7 months to 12 years-6 months), 248 children (9 years-4 months to 11 years-8 months) and 140 children (8 years-10 months to 12 years-10 months) in the three studies, respectively.

Investigating the relationship between trait and ability emotional intelligence and theory of mind.

Theoretical links between emotional knowledge and theory of mind (ToM) have previously been proposed. This study investigates this relationship using measures of both ability and trait emotional intelligence (EI). Our sample comprised 194 children, divided into two age groups (5-7 years and 8-10 years).

Implicit alcohol-aggression scripts and alcohol-related aggression on a laboratory task in 11- to 14-year-old adolescents.

Social scripts are commonly shared representations of behavior in social contexts, which are seen to be partly transmitted through social and cultural media. Research suggests that people hold scripts associated with alcohol-related aggression, but, unlike general aggression scripts, there is little evidence of social transmission. To demonstrate social transmission of alcohol-related aggression scripts, learning mechanisms based on personal experience should be minimized.

Alcohol-related image priming and aggression in adolescents aged 11-14.

In adults, alcohol-related stimuli prime aggressive responding without ingestion or belief of ingestion. This represents either experiential or socially-and culturally-mediated learning. Using a laboratory-based competitive aggression paradigm, we replicated adult findings in 103 11-14 year old adolescents below the legal UK drinking age.

Lies, damned lies and statistics? Reliability and personal accounts of smoking among young people.

Smoking remains a major problem among young people in Europe. However, within the research community examining the issue, debate continues about the best way of assessing the extent of that problem. Questions have been raised about the extent to which existing techniques for generating statistical representations of patterns of youth smoking can address a range of problems connected with identifying, accounting for and correcting unreliable self-report smoking data.
